If you are wondering what the next big thing will be in terms of social web, Facebook could probably answer that question for you. They have just developed Facebook Connect for Mobile Web. This will enable not only iPhone developers to integrate the power of Facebook with their apps but also enable users of any mobile device to use Facebook Connect. The company says that 65 million of its 300 million monthly active users accessed its site from mobile devices in August, that’s up from 20 million mobile users just eight months ago.

This is interesting you say, but what does this mean for me as a Facebook app developer? At the moment Facebook is looking into the idea of integrating apps into the Mobile Facebook app. More ways the user can access your application, enabling them to play your game for instance anywhere they have service on their cellphone. Imagine turning on your phone and seeing status updates from your friends about the latest game that they played with a link that you can click to join them in their quest. Talk about viral marketing. The competitive drive within us will help drive the viral marketing and increase the number of users that access your app on their mobile device.

At the moment Facebook developer team is still trying to make Facebook accessible with over 150 carriers in more than 50 countries. This is their top priority, but once that is done they might start to work on ways to get Facebook apps on mobile devices.

Nokia announced the release of the Facebook app this week. Facebook could potentially promote apps on the Ovi website (Nokia’s app store). The problem is that mobile devices have not historically allowed developers easy access to users. Nokia wants to become a serious competitor to iTunes and in order to do that it has to figure out a way to make its apps use Facebook data to help users find new games that they might want to play. If Nokia does that they will be able to increase the users for their apps and become a closer competitor to iTunes.
